Part II. Single Answer Questions (Select one answer only) - 16 marks On a production line, two factors affect the amount of waste generated during the production process. In an experiment conducted to understand the effects of the dust-level (Factor A: low, high) and the temperature (Factor B: low, high) on the waste level - Response) of the production process, the following results were obtained Factor B Temperature low high low 30 45 70 Factor A Dust-level high 6530 75 The higher the waste level, the more waste that is generated. 43 90 1. Which factor has a greater effect on the waste level: the dust-level (Factor A) or the temperature (Factor B)? A The effect of Factor A is greater than the effect of Factor B. B. The effect of Factor B is greater than the effect of Factor A C. The effect of Factor A and the effect of Factor B are the same There is not enough information provided 2. Continue to Question 1. What does the "Effect of Factor A" mean for this example? A. As the dust-level changes from a high level to a low level, the waste level increases by the number of units given by the Effect of A. B. As the dust-level changes from a low level to a high level, the waste level increases by the number of units given by the Effect of A. C. As the dust-level changes from a low level to a high level, the waste level is multiplied by the number of units given by the Effect of A. 3. Continue to Question 1. What statement with respect to interaction is correct? A. If the Factors A and B interact, it means that changing Factor A from a low to a high level will not affect Factor B. B. If the Factors A and B interact, it means that changing Factor B from a low to a high level will not affect Factor A. C. If the Factors A and B interact, only changing Factor A and Factor B together will have an effect on the response. D. If the Factors A and B interact, it means that changing at least one of the Factors from a low to a high level will change the effect of the other Factor
